The following recommendations will improve the chances of a successful overseeding. Apply any needed lime and fertilizer amendments. An up-to-date soil test will indicate which nutrients are needed for both established and growing plants. For more informa- tion, contact your local county Extension agent or consult the University of Kentucky (UK) publication Soil Sampling and Nutrient Management in Horse Pastures at Forage/agr200.pdf . Additionally, applying nitrogen in the fall can benefi t new seedings as well as most horse pastures. Spread two applica- tions of 30 to 40 pounds per acre of actual nitrogen 45 days apart to thicken stands and increase winter survival rates. Use high-quality seed of an improved variety . Use a seed variety that has proven to be a top performer under conditions in your area. The UK Forage Variety Testing Program looks at the seed- ling vigor, stand persistence, yield, and survival under horse grazing. Find this data in the Forage Variety Trials reports at foragevarietytrials2.htm . High-quality seed has good germination rates and is free of contamination from weed seed. Remember, quality seed will produce a pasture that lasts for years; "cheap seed" will only lead to headaches. Purchase seed well in advance, as quality seed will be in high demand close to planting dates. Store seed in rodent-proof containers in a cool, dry area. If you plan to store seed for more than six months, keep it in a refrigerator to maintain viability. Plant enough seed at the right time. Seeding rates are determined by the grass mixture you choose to plant. See Table 1 (above right) for the recommended seeding rates for common forage plants. Also, be sure to seed as early as possible—anywhere from mid-August to mid-September is ideal for Kentucky and most northern states, while later in the year is better in the Deep South). Use the best seeding method available. No-till drill seeding is recommended for overseeding existing pastures. But with any method, place the seed ¼ to ½ of an inch into the soil and cover it to achieve good seed-to-soil contact. Drill seed in two directions across the fi eld to ensure better coverage. Control competition. Close mowing or grazing prior to overseeding in the late summer and fall will reduce weed and grass competition. Be sure to follow recommended waiting periods when applying herbicides. In addition to limiting grazing of an overseeded pasture, limit herbicide applications at critical times. It's typically recommended to seed at least six weeks after spraying and wait until the grass seedlings are at least 4 to 5 inches tall before spraying again. Always follow herbicide labels—some of the newer herbi- cides have even longer waiting periods. For more informa- tion, see Weed Management in Grass Pastures, Hayfi elds, and Other Farmstead Sites at c agr172.pdf . Allow time for seedlings to establish. Returning horses to an overseeded pasture too soon can wipe out any seed- lings via grazing or trampling. Ideally, a pasture should have six months of rest after overseeding before heavy grazing resumes; however, seedlings can generally tolerate a few light grazing sessions. Harvesting the pasture once for hay after the grass has reached maturity and before returning B luegrass Equine DIGEST CA.UKY.EDU/EQUINE ❙ THEHORSE.COM ❙ JULY 2016 Tips for Overseeding Fall Horse Pastures In is Issue Estate Planning Tips for Horse Owners 02 The Grass Guide: Large Crabgrass 05 I'm Selling My Horse.
